Definitions

  • the invention pertains to a device for heating at least one tool that is disposed on the periphery of a rotatable cylinder.
  • German patent DE 44 014 48 B4 describes the provision of an induction heating coil structure in the interior of a cylinder.
  • the induction heater heats the entire circumferential surface of the cylinder and its flange.
  • German utility model DE 20 2008 016 510 U1 describes arranging a plurality of induction heaters distributed on the circumference of the shell of a roll, in order to be able to achieve regional heating of sections of the shell.
  • a rotatable cylinder comprising:
  • the rotatable cylinder is an embossing cylinder for embossing a printing material.
  • the printing material may be paper or plastic.
  • the at least one tool is formed of magnetizable material.
  • the cylinder shell and the sleeve-shaped carrier body are formed of a non-magnetizable material.
  • the cylinder body may be formed of a non-magnetizable material.
  • a single heater in the form of an induction coil is provided, the windings of which are laid around the circumferential surface of the cylinder.
  • a further advantage results from the lightweight structure of the cylinder body or of a sleeve-shaped carrier body arranged on the cylinder body, what is known as a “sleeve”, made of a non-magnetizable material, such as aluminum. This measure leads to a considerable weight reduction.
  • a rotatable cylinder that comprises the following: a cylinder body formed with a cylinder shell having a periphery; an induction coil configured to generate a magnetic field effective radially outside said cylinder shell; and a sleeve-shaped carrier body carrying one or a plurality of tools radially outside said cylinder shell, said carrier body being formed of non-magnetizable material and said one or more tools being formed of magnetizable material, so that the magnetic field generated by said induction coil selectively heats said one or more tools while said carrier body is not heated by the magnetic field.
  • FIG. 1 is a schematic sectional side view of a web-fed rotary press with an embossing unit
  • FIG. 2 is a schematic illustration of a longitudinal section taken through a cylinder according to the invention, the cylinder belonging to the embossing unit of the rotary press and carrying an induction-heated tool.
  • the press 1 is a label press, of in-line design, having printing units 2 , 3 , 4 following one another in the horizontal direction.
  • the press further includes a roll feeder 6 and a roll delivery 7 .
  • an embossing unit 8 Following the last printing unit 4 there is disposed an embossing unit 8 , which is used to emboss the labels.
  • the label press is used substantially for processing a substrate 9 in web form.
  • the substrate 9 is unrolled from a substrate roll 11 in the roll feeder 6 and guided along a path through the press 1 .
  • the substrate web 9 is printed, dried, embossed, etc. and ultimately rolled up onto a label roll 12 in the roll delivery 7 .
  • the printing unit 2 is constructed as a so-called flexographic printing unit.
  • the printing unit 2 has a printing form cylinder 16 and an impression cylinder 17 .
  • a UV dryer 18 is disposed underneath the impression cylinder 17 .
  • the printing unit 3 is likewise constructed as a flexographic printing unit, with a UV dryer 18 disposed laterally to the side of the impression cylinder 17 .
  • the printing unit 4 shows a flexographic printing unit with a hot-air dryer 19 arranged underneath the impression cylinder 17 .
  • the embossing unit 8 has two interacting cylinders 21 , 22 .
  • the substrate web 9 is guided through a pressure nip formed by the two cylinders.
  • a lower cylinder 21 serves as an impression cylinder for an upper embossing cylinder 22 .
  • the embossing cylinder 22 has a cylinder body 23 which is fabricated from a non-magnetizable material, for example aluminum, a ceramic composite material or a cubic face-centered steel.
  • An induction coil 24 is arranged on the cylinder circumference in such a way that the coil winding is wound over the circumference of the cylinder.
  • the coil winding is connected to a current generator 25 .
  • the embossing cylinder 22 bears a cylinder shell 26 in the form of a sleeve, which covers the induction coil 24 .
  • the cylinder shell 26 is produced from a non-magnetizable material.
  • a further sleeve namely, a “tool sleeve” 27 can be pushed laterally onto the cylinder shell 26 .
  • the tool sleeve 27 is produced from a non-magnetizable material, for example aluminum, ceramic composite material or plastic, etc.
  • the sleeve is a carrier body 27 for embossing tools 28 .
  • the embossing tools are produced from magnetizable material, for example cubic body-centered steel.
  • the induction coil 24 When the induction coil 24 is energized, by way of feeding current from the current supply 25 (e.g., a current generator G), a magnetic field is generated. This leads to the heating of the magnetizable materials that are located in the magnetic field of the coil. In the exemplary embodiment, these are the embossing tools 28 . Since all the further cylinder components are produced from non-magnetizable materials they are not heated by the magnetic field generated in the process.
  • the current supply 25 e.g., a current generator G
